LOCK-LATCH.

SLDECIFICATION forming part of Letters Patent No. 719,705, dated February 3, 1903.

Application tiled March 26. 1902. Serial No. 100.046. (N0 model-J all ill/11,0711, it' may concern.-

Beit known that I, MAXIME VALLE, a subject of the King of Great Britain, residing at St. Jerome, county of Terrebonne, Province of Quebecanada, have invented certain new and useful Improvements in Lock-Latches; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved doorfastening which is in the nature of a combined latch and lockmthat is to say,the metal tongue which forms the latch is adapted to be reciprocated and to be pushed into a socket, so that it also forms the bolt ot' a lock.

The object of my invention is to provide a fastening which shall dispense with unnecessary parts and utilize the latch-tongue simultaneously as a lock-bolt in the manner above referred to and to provide means whereby a single handle can be operated in connection with the key placed therein to withd raw the bolt of the lock and by the same operation raise the tongue of the latch.

In my improved construction I provide a metal casing or box containing a metallic tongue or bolt having a rectangular slotted extension cast integral therewith and having lugs or flanges thereon which engage with the sides of an eccentric mounted on a rotatable handle-spindle in such manner that the rotation of the handle will cause the said metallic tongue to reciprocate, and I further provide means whereby the rotatable handle-at one point of its revolution catches in the projecting metallic tongue and turns it about its own axis in the manner of a latch.

An important feature of my invention consists in the manner in which the said engagement between the rotatable handle-spindle and latch-piece is caused to take place. The eccentric mounted upon the handle has a notch in its periphery, in which engages a spring-pressed tongue carried by the slotted frame of the bolt or latch-tongue, so that when this pin is engaged with the eccentric the two will move solidly as one piece.

The most essential feature ot my invention, however, lies, perhaps, inthe manner in which the disengagement of the spring pressed tongue from the eccentric is brought about, and this consists in a small slidable releasing-bolt which is operated by a barrellock inserted into the interior of the rotatable handle-spindle, which is made in the form of a hollow barrel for this purpose.

As a special m odiication adapted for heavy doors Where locks are required to be much heavier than the fastening-latches I provide three or more bolts, each of which is adapted to engage in a suitable socket in the doorframe, but only one of which is adapted to act as a latch, and to this end the latch-bolt is mounted in the same manner as in the case where it is used alone; but the rectangular extension which it carries is provided with means for engaging with a frame on which the remaining bolts are mounted, so that the rotation of the latch-bolt as a latch will have no effect upon the other bolts; but its reciprocation as a lock will cause them to be reciprocated sim ultaneously with it to be drawn or shot.

Myinvention further consists in the peculiar construction and combination of parts which will be hereinafter described, and particularly pointed out in the claims.

I have illustrated my combination locklatch in the accompanying drawings, Where- 1n- Figure l is a perspective view of the ordinary -form of my lock-latch as attachedto a door.

11 is a similar view of the parts constituting the locking mechanism, the several parts being shown in separated positions in order to more clearly illustrate their formation and mode of combination. Fig. 12 is a perspective View of a key adapted to operate the. lockbarrel.l Fig. 13 is alongitudinal section taken just beneath the face-plate of a modified form of my improved lock-latch especially adapted to heavy doors and showing the same in locked position. Fig. 14 is a similar view to Fig. 13, showing the fastening in unlocked position; and Fig. 15 is a central longitudinal section of a slightly-modified form of locking-barrel.

The same numerals of reference denote like parts in. all the figures of the drawings.

Referring first to the form of lock shown in Figs. 1 to 5, inclusive, 16 designates the casing or box of the fastening, this box having a cover-plate 17 on the back thereof, to which it is attached by means which will be hereinafter referred to. The box or casing is of an approximately,rectangular form,

being formed, as in the drawings, with its upper and lower sides 18 and the free side 19 opposite to the locking-face of the fastening slightly concave for ornamental purposes, and through the casing and its cover are formed holes in the four corners thereof, through which are inserted screws or like fastenings 2O for attaching the lock-latch to the door 15. In the center of the box 16 is also formed a transverse circular aperture 21 of sufficient size for the insertion of the hollow handle-spindle 22, and the cover-plate 17 is formed with a similarly-formed aperture 23 for the same purpose. The hollow spindle 22 carries fixed thereto an eccentric sheave 24, the throw of which-that is to say, the double distance of its center from the center ofthe handle-spindle-is equal to the throw ot' the latch-tongue in the locking operation, and in the edge of the sheave 24, diametrically opposite the handle-spindle, is formed a square transverse notch 25. The eccentric sheave when the lock is in place is located at the bottom of the box 16-that is to say, at the front portion thereof-and engages with the latchpiece to reciprocate and oscillate the same in a manner which will be presently described.

The latch-piece proper (designated as a whole by 26) is shown by itself in detail view in Fig. 9, and it consists of an outwardly-extending latch-tongue 27, which is destined to perform the simultaneous function of a locking-bolt, as will hereinafter be shown, and of a rectangular extension or frame 28, which is centrally slotted, as shown at 29, the ends of the slot 29 being semicircular and its diameter being the same as the exterior diameter of the hub-liange 30, carried by the eccentric sheave 24, so that the handle-spindle 22 and the hubtlange 30 project through the slot 29, and the latch-piece has a certain reciprocation thereon equal in extent to its throw when reciprocated as a lock.

At each end of the rectangular extension or frame 28 are formed two lateral hanged lugs 31, which extend across from top to bottom and contain between them the sheave 24, the distance between the inner faces of these two lugs being exactly equal to the diameter of the sheave. Each of the lugs 31 is transversely slotted in the center, as shown at 32, and in the slot travels a small block or tongue 33, which is longer than the thickness of the lugs 31, so as to project from the inner face of the latter when pressed inwardly by the spring 34, which is attached thereto at one end and at the other end is bent back, as at 35, and inserted into an appropriate recess 36, formed in the end of each lug 31. It will thus be seen that the two tongues 33 are pressed against the face of the eccentric sheave so as to drop into the notch 25 when the latter is brought opposite to one of them,

as shown in Figs. 2 and 4.

The operation of the two moving parts within the case 18 will be readily understood, and these two moving parts constitute the main features of the lock-latch mechanism, which is therefore one of great simplicity. When one of thev handles 37, which are carried upon the respective ends of the spindle 22 and secured thereto in any suitable manner, as by screws 38, is rotated, supposing for the moment that neither of the tongues 33 engages in lthe notch 25 of the sheave, the latter will cause the latch-piece to be rst projected outwardly into the position shown in Fig. 2, whereby it will be caused to be locked in a socket provided for it, to be hereinafter described; but when rotated in the opposite direction the sheave will retract or draw the tongue 27 into the position shown in Fig. 4, and in this position it will be seen that the rear tongue 33 will drop into the notch 25, so as to secure the latch-piece fast to the eccentric sheave, and thereby to the handle-spindle, and the further rotation of the handlespindle in the proper direction will now cause the latch-piece to be rotated about the handle-spindle as an axis into the position shown in dotted lines in Fig. 4, this rotation being enabled by the slot 39 in the side face of the lock-casing being made of extra width for this purpose, as shown in Fig. 4, and the ro tation of the latch-piece .in this manner will cause a disengagement of the tongue 27 from the catch-dog, to be presently described.

The catch-piece which 1 use to coperate with the tongue 27 is a compound catch and bolt-socket corresponding to the compound nature of the lock, and it is shown in detail in Fig. 10. This catch-piece is of improved form, having the base-plate 40 provided with a rectangularly extending flange or edge plate41, which is adapted to extend over the edge of the door-jamb and to be mortised thereinto and to be secured by screws or other fastenings passing through holes 42, formed transversely in the plate 41, while the baseplate 40 may be likewise provided with addi- IIO tional screw-holes 43 for the insertion of screws 44. Projecting from the front of the base-plate and close to the edge of the door-jamb is the catch 45, which is of the ordinary type, having an upper oblique camface 46, adapted to catch and raise the latch when the door is being closed, and a shoulder or dog 47, adapted to catch and hold the tongue 27 when it drops thereinto, and is supported upon a seat 48, which is on a level with the lower edge 49 ot the slot 39 in the lock-casing. The plate 40 has also projecting therefrom, just back of the catch 45 and preferably formed integrally with said plate, a boltsocket 50, which is adapted to receive the end ofthe tongue 27 when shot thereinto bythe rotation of the sheave 24,as just described,and to this end the upper edge 5l of the socket is so positioned that the tongue 27 will be contined thereby when projected into said socket and prevented from rising from its seat 48 upon the catch 45, thus preventing the rotation of the tongue when in its locked position, so that the cover of the socket 50 and the dog 47 act simultaneously to prevent the opening of the door by pressure from the rear or outer side thereof.

Describing now the casing 16 of the lock, this is shown in detail in Fig. 6. From that ligure it will be seen that the edge piece 52 is prolonged into an edge plate or flange 53, adapted to overlie and to be mortised into the edge of the door in the same way as the flange 41 overlies the edge of the door-jamb, and it is similarly adapted to be attached to the edge of the door by screws inserted through holes 54, whereby the attachment of the lock to the door is very greatly strengthened and the fastening is prevented from being torn off by any ordinary means. The mode of attachment of the cover-plate 17 to the inner face of the casing 16 consists in a pair of snugs 55, which are formed on the edge adjacent to the plate 53 and are adapted to Vfit into corresponding recesses 56, formed in the plate 53. On the opposite side of the cover-plate and centrally thereof is provided a screwhole 57, through which is passed a screw 58, and is embedded in a suitable female-threaded screw-lug 59, cast vupon the side 19 of the box 16, and in order to further secure the cover-plate against displacement I may provide suitable snugs 60, projecting from the interior face of the cover-plate and abutting against the inner faces of the sides 18 and 19 of the box 16, so that when the snugs 55 are inserted into the recesses 56 provided for them and the screw 58 inserted in its socket the cover-plate will be firmly secured against disturbance.

I will now describe the method by which the tongues 33 are released from the notch 25 when engaged therewith in order to lock or unlock the door. As will be seen from Figs. 2 to 5 and Fig. 8, the handle-spindle 22 is made in the form of a. cylindrical barrel, and mounted centrally within the spindle 22 there is a locking-barrel 61, which is of external diameter the same as the internal diameter of the spindle 22, so that it may be inserted and held against lost motion therein. The locking-barrel 61 is prevented from turning within the spindle 22 by a releasing-bolt 62, which is secured to a part thereof and projects outwardly through an aperture 63 in the spindle and through a socket G4, formed longitudinally through the center of the eccentric sheave, the axis of this socket being coincident with the diameter common to the center of the spindle 22 and the notch 25, so that the releasing-bolt is adapted to be projected forwardly in its socket and into the notch 25, as shown in Fig. 3, to raise the tongue 33 out of said notch, whereby the eccentric sheave may be turned.

The locking-barrel 6l is formed at either end of the same diameter as the inner diameter of the spindle 22, as hereinbefore mentioned; but it has between the two ends thereof and close to that end which is on the inside of the door-that is to say, on the side on which the casing of the lock is attached-an annularly-reduced portion 65, and from this annularly-reduced portion 65 a segment upon one side is cut away, the recess thus formed being adapted to be filled by asegmental block 66 of shape corresponding to the cut-away portion and having on its extremities a pair of projecting lugs 67, adapted to reciprocate within two radial slots 68, formed on the respective flanks or shoulders of the reduced portion 65, as clearly shown in Fig. 11.

Through the center of the locking-barrel 6l is formed an axial bore 69, and this bore is hollowed or scooped out opposite the segmental recess in the reduced portion 65 through an arc slightly exceeding a semicircle, as clearly shown at 70 in Figs. 2, 3, and 4, thus forming a recess for the operatingfeather 7l upon the end of the shank 72 of the key 73. The segmental block 66 has in IOO lio

its outer face a screw-threaded socket 74,

into which is screwed a stud 75, which is formed on the end of the-releasing-bolt 62, this stud 75 being of smaller `diameter than the bolt 62, so as to form a lshoulder 76 at the inner end of the bolt, and between this shoulder and the face ot' the block 66 is secured a circular plate-spring 77, which is adapted to lie in the annular recess 65 and to embrace the barrel 6l and block 66, so as to hold them together, and in the center of the spring 77 is formed a hole 78 of just sufficient diameter to fit over the stud 75, so that when the latand thereby the releasing-bolt 62 is projected into the notch 25 and the tongue 33 is released therefrom, whereupon rotation of the handle 37 will cause the latch-tongue 27 to be shot into or withdrawn from the socket 50, as the case may be.

In order to prevent the Operation of the releasing-bolt by any key that maybe inserted into the lock having a proper operatingfeather, I provide a locking-feather 8O upon the shank 72 of the key, this feather being located above the feather 7l and being formed, preferably, to project in both directions from the shank 72 and having steps 8l symmetrically formed on the two opposite halves of the feather and adapted to coperate with similarlyformed grooves or wards 82, formed within the locking-barrel 6l at the end thereof opposite to the recess 65, and in order to enable the insertion of the key in the barrel the bore 69 is widened out into a diametrical slot of sufficient width for the widest part of 'the two feathers 7l and 8O to pass therethrough, as will be well understood. That end of the locking-barrel adjacent to the inner handle 37 is not provided with grooves or wards 82, because ordinarily it will not be desired to prevent people from opening the door from the inside, so that such provision will be unnecessary.

When the key 73 is inserted through the keyhole 79 in the handle and into the locking-barrel 6l and is brought to its seat by any suitable contrivance-as, for instance, by a shoulder 83, formed on the base of the feather 80the steps 8l will then mesh with the corresponding grooves 82, and the key may be turned so as to press the segmental block 66 upwardly and release one of the tongues 33 from the notch 25, when, supposing the bolt to be shot and the apparatus in the position shown in Fig. 3, the handle may be rotated in either direction through a half-revolution until the notch 25 comes opposite the other tongue 33, which will thereupon dropthereinto, the segmental block and releasing-bolt having been meanwhile snapped back into place by the slight overturning of the key. When in this position, (shown in Fig. 4,) the latch-tongue will be engaged with the catchdog 47 and may be released therefrom by slightly rotating the handle to the left., when the parts will assume the positions shown in dotted lines in Fig. 4. In shooting the bolt 27 to lock the door the same operation of inserting and turning the key will be performed and the handle will be again rotated a halfrevolution in either direction until the forward tongue 33 snaps into the notch 25, when the projection of the tongue 27 into the socket 50 will prevent the handle 37 from being further turned in either direction until the key is again brought into service.

As a slight modification of the releasingbolt mechanism shown in Figs. and 11, I provide that shown in Fig. 15, wherein the bottom of the reduced portion 65 is provided with two lateral grooves 65a, and the segmental block 66', corresponding to the block 66, has corresponding grooves 65b formed around the ends thereof, and in these grooves are seated a pair of circular springs 77 of the same form as the spring 77, only narrower, these springs 77l being adapted to take the place of the spring 77, as will be seen. However, the cylindrical barrel-releasing mechanism shown in Figs. ll and l5 is by no means essential to the operation of myinvention, for I may substitute other means for reciprocating the bolt 62 than that herein shown, the locking-barrel mechanism shown being simply that preferably used by me in the present form of the device.

In cases Where very heavy doors are to be locked and correspondingly-heavyboltsare required-as, for instance, in store-room, maga- Zine, or safe doors-I may provide the special form of latch-lock shown in Figs. 13 and 14, and this form comprises a plurality of locking-bolts, only one of which is adapted to act as a latch-tongue in the manner hereinbefore described and all of which are arranged to be shot and drawn simultaneously with said latch-tongue. In these figures the casing of the lock is designated by the numeral 16, and it has screW-fastenings 20'and a screwlug 59 of precisely the same nature as the fastenings 2O and the lug 59 in the first form described. The hollow handle-spindle 22, carrying the notched eccentric sheave 24, and the releasing-bolt mechanism carried thereby are of precisely the same form as those before described; but the latch-piece 26 is of slightly-different form, having the rectangular frame 28 thereof formed to cooperate with the larger rectangular bolt-frame 84. This bolt-frame 84 is formed, as shown, of two reciprocating bolts 85, respectively above and below the central latch-piece and connecting tenons 86 at the front and rear of the rectangular frame 28 of the said latch-piece. This frame 84 is guided to reciprocate back and forth horizontally by suitable snugs 88, projecting from the inner face of the cover-plate 17, and to cause this reciprocation the tenons 86 are adapted to have contact with the edges of the frame 28', each tenon 86 carrying a pair of friction-rollers 87 on inwardly-projecting bearinglugs 88 formed thereon. The rollers 87 roll upon the outer edge 89 of the frame 28', this edge being formed circular and concentric with the axis of the handlespindle 22, so that when the latch-tongue 27 is withdrawn and turned to act as a latch this will occur without any movement of the boltframe 84, as clearly indicated by the dotted lines. It will thus be seen that While the reciprocation of the latch-piece 26' will cause the simultaneous reciprocation in the same direction of the bolts 85, yet the tongue 27 can be readily raised and lowered in its withdrawn position without in any way aecting the movement of the bolts 85. On the contrary, these will be held in withdrawn posi- IOC IIO

IIS

tion and with their faced ends fiush with the edge-plate 52' of the box 16 of the lock. Corresponding with this modified form of lock-latch, I provide a similarlymodified form of catch-piece, the base-plate of which is extended to the length of that of the box 16', and it has three sockets therein, (numbered,respectively, 50', 50a, and 50b,) the first being arranged to act in conjunction with the catch as before described, while the two side sockets and 50b are close to the edge ofthe door-jamband positioned to receive the ends of the bolts 85, as shown in Fig. 13. The catch-piece may be secured to the door by means of suitable screws 4A', and it is otherwise formed, preferably, in a similar manner to the catch-piece shown in Fig. 10.

The advantages presented by my improved latch-lock will be obvious to all in that they not simply dispense with unnecessary parts and great-ly contract the size of the doorfastening, but also providea rapid and ready means for unlocking the door by a single handle, and it will be observed that after the key has released the tongue from the eccentric sheave and the latter has been turned slightly a further rotation of the key will cause the barrel and the handle itself to rotate, so that all that will be necessary will be simply to turn the key, as the friction of the key-feather 7l upon the interior of the segmental block 66 will generally suffice to turn the eccentric sheave out ofengagement with the tongue 33 when the latter has once been pushed out of its seat in the notch. A further advantage is that the time lost in searching for a keyholein the dark or in trying to insert the key into the keyhole of an ordinary lock is minimized, because the keyhole in my lock-latch being precisely in the center of the handle it can be found at once by the sense of touch and without it being necessary to see where the keyhole is. In the modified form used for heavy doors the advantage of having a simple latch and a compound lock both operated by the same handle will be apparent in that it decreases the strength necessary' to operate the latch and provides a latch-fastening mechanism not ordinarily present on such doors, which are in general provided simply with bolts.

Vhile I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without 'affecting the operativeness or utility of my invention, and I therefore reserve the right to make such modifications as are included in the scope of the following claims.
